A drainage system for highway bridges

Abstract

The invention discloses a drainage system for highway bridges, which comprises a drain hole set on the upper part of the road surface, a drain pipe vertically inserted on the inner wall of the drain hole, a water seepage cover set on the top of the drain pipe, and a water seepage cover The upper part is provided with a plurality of first permeable holes, and the inside of the drain pipe is provided with a collection assembly. A horizontal bar is connected between the inner side walls of the ring, and a vertical pipe is fixedly connected to the horizontal bar. The upper part of the vertical pipe is provided with a cone, and the bottom of the cone is provided with a tapered groove. The vertical pipe is fixedly connected to the inner top surface of the tapered groove. , the vertical projection of the outer edge of the bottom of the cone falls inside the arc ring; the upper part of the arc ring is provided with a plurality of second permeable holes, and the apertures of the second permeable holes are smaller than the apertures of the first permeable holes. The invention has the effect of collecting sundries smaller than the inside of the drain pipe cover, so that the drain pipe drains smoothly.

Description

Technical field [0001] The present invention relates to the technical field drainage pavement, road bridges particularly to a water drain system. Background technique [0002] Currently, with the rapid development of public transport, bridges across rivers and because of its shorter road mileage and other characteristics of a large number of construction, especially for use on the highway bridge, in order to improve the service life of the bridge, construction workers are provided on the bridge drainage structures. [0003] Existing announcement CN209584829U number of Chinese patent discloses a highway bridge drainage system, including a full collection drainage system, characterized in that: the system is also provided with a straight row, in-line system include higher deck drain port, vent outlet pipe directly into the water. Drain port of the colinear system drain intervals between full collection drainage system disposed within said drain opening with a drain pipes, drain pip...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the large-grained debris on the road surface of the highway bridge is blocked by the drain pipe cover, but some medium-grained debris will flow into the drainpipe along the groove on the upper part of the drainage irrigation, and the drainage The interior of the water pipe may be blocked by sundries, making the water flow in the drain pipe unsmooth, resulting in accumulated water on the upper part of the road surface that cannot be discharged
